ABSTRACT: The brown shrimp Crangon crangon is a key component of the North Atlantic coastal food web and an important target species for the fishery economy. As the brown shrimp contains large amounts of protein and essential fatty acids, its consumption makes it a beneficial choice for humans. Commercially harvested crustaceans like C. crangon are frequently affected by bacterial shell disease, with necrotizing erosions and ulcerations of the cuticle. To determine whether shell disease influences the nutritional value of C. crangon, total protein and lipid contents, as well as fatty acid compositions of muscle tissue and hepatopancreas, together with the hepatosomatic index, were examined in healthy and affected individuals. The biochemical composition of the tissues did not differ significantly between the 2 groups. Also, the hepatosomatic index, as an indicator of energy reserves in shrimps, was similar between healthy and affected animals. Our results indicate that the nutritional value of C. crangon is not affected by shell disease, as long as it remains superficial as in the present study.

贝壳病不会影响北海褐虾Crangon crangon的生化特性。

摘要：棕色虾Crangon虾是北大西洋沿海食物网的重要组成部分，也是渔业经济的重要目标物种。由于棕色虾含有大量蛋白质和必需脂肪酸，因此它的食用使其成为人类的有益选择。商业收获的甲壳类动物，如C. crangon，经常受到细菌性壳病的影响，坏死性剥蚀和角质层溃疡。确定贝壳病是否影响C. crangon的营养价值检查健康个体和受影响个体的总蛋白和脂质含量，以及肌肉组织和肝胰腺的脂肪酸组成以及肝体指数。两组之间的组织生化组成没有显着差异。同样，健康和受影响动物的肝体指数（作为虾中能量储备的指标）也相似。我们的结果表明，只要象本研究一样保持浅浅，C。crangon的营养价值就不受壳病的影响。
